The Options window allows you to manipulate the cosmetics
of your plot. You may change the color, graph type, the labels,
the axes, the tick marks, etc. This is very helpful if you have
more than one graph showing, in that you can specify particular
colors and legends to help clarify. If you are only graphing
one plot at a time, then this option will let you tidy the results.
The Axes window has a number of options
available. The first of these are basically light switches that you
turn on and off by clicking on them. Watch your graph change as
you change the switches from to
- Grid: Will make a background grid for the graph
- Box: Will create a box around the graph
- Plot Legend: Allows you to see the plot with or without the legend
- Auto Scale: Redraws the plot with scale automatically calculated f
- Axes: Allows you to turn axes on and off
- Numerical Labels: Turns the numbers on the axes on and off
- Axes/Title Labels: Turns axes and title labels on and off
There is also the option to change the range and the domain graphed
of the function. To do this, place the mouse in the desired window,
and change the number to your satisfaction. Once you have changed
all the values you didn't like, click on the
If the values you chose
are valid (in that the function exists within those parameters), the
graph will automatically change to reflex the new ranges. If not,
however, you will receive an error message telling you that the
function does not exist at a certain point. Be familiar with the
limitations of your chosen function.
You may also change the tick marks on the axes. Enter in the
desired interval for the major tick marks, and choose between
0 and 10 for the minor tick marks (you may use the slide on the
side of these with the middle mouse button
if you find that easier). Again, once you have
changed the numbers, click on the
Attributes has four
sections (Plot Type, Line Type, Marker Type, and
Points to Be Displayed) all dealing with
the type of graph you are going to be viewing.
- 3D are comprised of a line connecting each value along the X axis.
The plot is formed of a series of connected lines stacked in the Y direction.
- Scatter interpret input as a set of individual points,
and are displayed as such.
- Impulse plots are formed by extending a line from the
floor of the 3D plot upward in the Z direction.
The height of each line in the plot represents the value at that particular
- Mesh ,similar to 3D plots, are pictured as a surface
map make up of polygons rather than as a set of lines.
- Horizon are drawn from the rear to the front.
It implies that the under surface will be filled.
- Surface : similar to Mesh plots, except the surface is colored.
- Contour 3D The contour lines supply depth information. The
contour levels are represented by their colors, and depth information
is also represneted by the position in the 3D space.
- Contour 2D take 3D information and display it in a
2D space. The contour lines on the XY plane supply depth information,
as in aerial photography and relief maps. The different contour levels
are represented in different colors in the order of ROYGBIV.
- Color Mesh is a colored mesh plot.
Color is a function of the height of the values in the Z direction.
Of all of the windows you will open in your lifetime,
this one has
to be the most self-explanatory. In this window,
you may change the:

Your font options are in Figure 11.

Make sure that when you are changing the titles, you have the mouse
in the box you wish to write in. Those arrows at the ends of the boxes
tell you that you must hit enter/return once you have finished
editing the particular title. (Remember to hit enter/return
for each edited title!)

I find this one (Figure 12)
of the most satisfying tools there is.
You may very easily change the color of
anything within the graph, except the background color of black.
What you may change:
This is, of course, assuming that you have clicked these options
Axes section. If they are , then
you will not receive an error message, but then again, nor will you
see any result. This lovely package gives you a huge
selection (Figure 13) to choose from.
Below is the opening image for this tutorial. I have turned off the
plot legend, as well as changed the colors of everything I could change.
Remember that this is a plot of the function
f(x) = sin(x²)-2cos(y²)-x³y³ from the previous section.
